Maps of China and the world
{"Image ImageDescription": "Image 1 of 2. Maps of China and the world. Historical maps depicting the Ming Empire of China (left) and the world (right), with China at the centre. The Yellow (upper) and Yangtze (blue, lower) rivers are clearly seen. The world map depicts China as an island surrounded by water and an all encircling world. The Great Wall of China, started in 7BC, is seen on both maps. The wall was renovated during the Ming dynasty, which began in 1368. This map is believed to date from around 1800, but may have been based on an earlier map of unknown date. Text written on the reverse of the sheet can be seen faintly.
